Mutational Analysis of TCOF1, GSC, and HOXA2 in Patients With Treacher Collins Syndrome
Treacher Collins syndrome is an autosomal dominant craniofacial malformation mainly caused by mutations in the TCOF1 gene. Few cases have been observed in the Chinese population. Herein, the authors report the mutational analysis of TCOF1, GSC, and HOXA2 to determine the mutational features of the 3 genes in Chinese patients with Treacher Collins syndrome. Genomic DNA of the patients and their ...
متن کاملTreacher Collins Syndrome
Treacher Collins syndrome (TCS) is a genetic disease that alters the development of bones and other tissues in the face, and presents variable expressivity. At least three genes TCOF1, POLR1D, and POLR1C were recognized to be at the origin of this syndrome which may be inherited through either an autosomal dominant or autosomal recessive pattern. TCS changes can be divided into otological, opht...
متن کاملTreacher Collins syndrome TCOF1 protein cooperates with NBS1 in the DNA damage response.
The signal transduction pathway of the DNA damage response (DDR) is activated to maintain genomic integrity following DNA damage. The DDR promotes genomic integrity by regulating a large network of cellular activities that range from DNA replication and repair to transcription, RNA splicing, and metabolism. In this study we define an interaction between the DDR factor NBS1 and TCOF1, a nucleola...
متن کاملThe Treacher Collins syndrome (TCOF1) gene product is involved in pre-rRNA methylation.
Treacher Collins syndrome (TCS) is characterized by defects in craniofacial development, which results from mutations in the TCOF1 gene. TCOF1 encodes the nucleolar phosphoprotein treacle, which interacts with upstream binding factor (UBF) and affects transcription of the ribosomal DNA gene. The present study shows participation of treacle in the 2'-O-methylation of pre-rRNA. Antisense-mediated...
متن کاملRegulation of the mouse Treacher Collins syndrome homolog (Tcof1) promoter through differential repression of constitutive expression.
Treacher Collins syndrome is an autosomal-dominant mandibulofacial dysostosis caused by haploinsufficiency of the TCOF1 gene product treacle. Mouse Tcof1 protein is approximately 61% identical and 71% similar to treacle, and heterozygous knockout of Tcof1 causes craniofacial malformation. Tcof1 expression is high in developing neural crest, but much lower in other tissues. To investigate this d...
